Description
Technical field
The utility model belongs to field of steel metallurgy, and in particular to a kind of aqueous vapor double containment converter movable hood.
Background technology
The gasification cooling flue part of Converter Residual Heat Boiler is provided with converter movable hood, goes out toward converter hot metal charging or converter
During steel, movable gas hood must be lifted up, so as to converter can smooth lateral rotation, during Converter Oxigen Blowing, movable gas hood is dropped
Under, reduce the gap between movable gas hood and converter, to reduce the air for being inhaled into gasification cooling flue, reduce by furnace gas
CO combustion rates, improve coal-gas recovering quality.Working environment residing for movable gas hood is very severe, receives high-temperature furnace gas periodically
Wash away, nearer from converter mouth, when converter splash, movable gas hood is also easy to that dross occurs, to ensure that movable gas hood smoothly enters
Row lifting cover acts, and the design size of movable gas hood is typically greater than the size of converter mouth, i.e., in movable gas hood and Converter
Certain gap is left between body, therefore although having carried out drop cover operation in Converter Oxigen Blowing, still can be by a certain amount of air
As coal gas of converter sucks gasification cooling flue together, cause in flue coal gas of converter to burn and cause coal gas of converter temperature liter
Height, and the rise of coal gas of converter temperature may cause the devaporizer entrance overtemperature behind waste heat boiler, and the air sucked is led
CO burnings reduce the quality of gas recovery in cause flue, it is therefore necessary to the air capacity of suction is reduced as far as possible, meanwhile, although converter
Waste heat boiler afterbody has dedusting fan to aspirate coal gas of converter, but still has many furnace gases from movable gas hood with turning in actual production
The gap China and foreign countries of stove are overflowed, and workshop air is polluted.
The movable gas hood used at present in engineering is generally divided into independent hermetic seal or two kinds of independent water-stop, hermetic seal are exactly
Substantial amounts of sealing gas jets are set on movable gas hood top, and during Converter Oxigen Blowing, these nozzles spray blanket gas, form a circle gas
Curtain, to completely cut off extraneous air, and prevents furnace gas from leaking, but is found in Practical Project, still has air to be burnt into flue, and
And oxygen blast it is violent when, furnace gas can also leak at air curtain, cause in workshop pollute, water-stop be then movable gas hood top set
Water sealed tank, in fire door section flue water seal plate is set, water sealed tank and water seal plate cooperatively form water seal, by furnace gas in petticoat pipe with it is outer
Boundary thoroughly isolates, and the effect of this isolation is better than hermetic seal, but due to preventing from gluing between movable gas hood bottom and fire door
Slag causes movable gas hood can not lift the gap that must stay more than 50mm, so outside still a small amount of after the meeting air entrance or flue gas
Let out.
Utility model content
The purpose of this utility model is to provide a kind of aqueous vapor double containment converter movable hood, the movable gas hood by water-stop and
Hermetic seal combines, and hermetic seal is located at into bottom, can reduce inhaled air volume and reduce flue gas and leak, reduce in flue
Gas-fired rate, improve coal-gas recovering quality.
Technical scheme is used by the utility model：
A kind of aqueous vapor double containment converter movable hood, upper header, heat pipe are sequentially provided with from top to bottom inside movable gas hood
And lower collecting box, heat pipe connect upper header and lower collecting box to form truncated cone-shaped heating surface, top is provided with outside movable gas hood
For the annular water sealed tank being filled with water, the water seal plate of annular is fixed with fire door section flue, water seal plate is always positioned at water seal
Water seal is formed in groove, the blanket gas header of annular is provided with below movable gas hood, sealing gas jets are evenly equipped with blanket gas header, it is close
Envelope gas header is connected to sealing source of the gas.
Further, blanket gas nozzle exit is nozzle orifice plate, has several apertures in nozzle orifice plate.
Further, the aperture in nozzle orifice plate is divided into centre bore and remaining hole, and remaining hole is uniform by the center of circle of centre bore.
Further, blanket gas header is located on the inside of lower collecting box.
The beneficial effects of the utility model are：
1. the movable gas hood combines water-stop and hermetic seal, and hermetic seal is located at into bottom, it is empty that suction can be reduced
Tolerance simultaneously reduces flue gas and leaked, and reduces gas-fired rate in flue, improves coal-gas recovering quality.
2. the blanket gas of ejection can be divided into multiply air-flow by nozzle orifice plate, it is easy to form air curtain.
3. by around the center of circle it is uniform in a manner of distribute air-flow, while improving air-flow coverage, ensure that the uniform of air-flow.
